IMHO, you just hold a crypto that you think that has long term potential, either you earn or you lose it's value you must be ready for that before entering. As OP stated the dangers of a hodler, take into consideration not to do those things, this is not a financial advice but a worthy and humane one, take it from the HODLers
Danger or risk, it's the same, once we buy a coin and we hold it, the risk starts as we can loss our money too.
Our purpose is to make profit either short term or long term, but if we are confident with what we are holding, we will never get panic because we
know it has its time to rise. Investors who easily panic has no room for success here in crypto.
